ISL88001IE26Z-TK

Supervisors Overview

The ISL88001IE26Z-TK is a single-channel voltage supervisor IC manufactured by Renesas Electronics. It monitors input voltages within a range of 1.8 V to 5.5 V, featuring a fixed threshold of 2.63 V with ±1.2% accuracy. The device provides an active-low push-pull reset output and includes a 190 ms reset delay timer. Operating at a maximum supply current of 350 nA, it supports overvoltage detection at 2.662 V and under-voltage detection at 2.598 V. Packaged in SC-70-3, it operates between -40°C and +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with fixed threshold options for standard power rails
• Features ultra-low quiescent current consumption suitable for battery-powered applications
• Delivers active-low push-pull reset signal with defined delay timing

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing reliable power management
• Embedded circuits utilizing standard logic voltage levels

Supervisors Procurement Notes

Verify the specific suffix 'TK' indicates tape-and-reel packaging when ordering. Confirm the exact threshold voltage variant matches design requirements, as the family offers multiple fixed options. Check manufacturer notices for end-of-life status or product change notifications affecting availability or specifications before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel supervisor with push-pull output is required for low-voltage monitoring. Ensure the 2.63 V threshold aligns with the target rail voltage. Consider the SC-70-3 package size constraints and the 350 nA standby current impact on overall system power budget during selection.

Supervisors Part Context

This part belongs to the ISL88001 series of single voltage monitoring supervisors from Renesas. The series is designed for portable electronics and battery-powered equipment. It complements other variants like the ISL88002 which may offer different output types or thresholds within the same functional family.

Supervisors Replacement Considerations

Direct substitutes include other ISL88001 variants with matching threshold voltages and push-pull outputs. Verify pin compatibility and electrical parameters against datasheets before substitution.
